It's nothing special yet, but this is the Japanese version of Warriors Orochi 3 (which isn't out yet in the EUR/US)
Warriors Orochi 2 was VERY fun (So I'm VERY excited to see how WO3 looks like). But I forgot, in Japan they didn't consider Warriors Orochi 2 as a sequel, they considered it Warriors Orochi EX if anything. Which is why they are calling this one, their #2.
